MACHINE FOR MAKING WIRE-BALE-TIE LOOPS.

To all whom it mayy concern: n

Be it known that I, RowLAND J. DARNELL, a citizen of the Unit-ed States,residing at Memphis, in the county of Shelby and State of Tennessee,have invented certain new and useful Improvements in Machines for MakingVVire-Bale-Tie Loops, of which the following is a specification. y

My invention relates kto a machine for lmaking wire bale-tie loops, moreespecially` to such a machine inwhich` the wire shall be fed inautomatically the required length, cut,'a loop formed on the end of thewire from which the piece has vbeen cut, then the wire further fed intothe machine therequired-distance and again cut, repeating the operationsin successive cyclesvof the machines action. i

VItis an especia-l object of my invention to provide a looping devicewhich shall form on.. the end of the wire a double coil loop, said loopbeing finished by wrapping the end of the wire cleanly severaltimesabout the wire shank, in combination with means for actuating thelooping mechanism and thereafter actuating feeding and cutting mechanismso that the series ofv kopera-tions l is automatic, correlated, andcontinuous, and

a high speed in the manufactureof the loops may be attained. i

' The full objects and advantages of my invention will appearinfconnection with the detailed description thereof and are particularlypointed out in the claims.

In the drawings, illustrating the applica-y tion of my invention in oneforum-Figure -1`1s a plan view of my machine. Fig. 2 is a longitudinalsection from front to rear thereof. F ig. 3 is a transverse sectionalview of a portion of the Vmachine showing the cam shaft and relatedparts viewedy toward the front of the machine. Fig. L tis a .detail viewof the intermittent gear feed rmechanism. Figs. 5 and 6 are views ofwing-cams and cooperating shift-ing members actuated thereby. Fig. 7 isa view of acompleted bale-tie made on my machine.

In the practice of the artto which my invention relates, it has beencustomary to form loops by twisting together the return h end of thewire and the vshank of the wire,

both members being twistedy or coiled about the other. This involves ayweakened pointy 1 Specification of Letters Patent. Application iedApril 8, 1.912." Serial No. 689,301.

in the wir@ Shank itself which may break under excessive strain. Loopshave been formedv 1n somewhat the manner 1n which I form my loops bymechanism operated largely by hand, entirely so as regards the feed ofthe wires into the machine. In machines of this type where the wireshave torbe fed` in by hand,-they mustA be cut into the proper'lengths inadvance of such feeding,` and the operation of feeding them in onek atka` time by hand is necessarily vrslow and vproduces imperfect results.One of the in the fact that the feed ofthe wire is from Patented Dec.y24,1912.

e5 primary advantagesof 'my machine resides a coil as it comes from thefactory and is i absolutely continuous so that the loops are formed, thewires fed forward vthe proper distance and then out off and deliveredfrom the machine by an automatic and continuous series of operations.The machine, therefore, can be driven at a high rate of speed andwilloperate to loop and deliver a maximum of near one hundred bale-tiesperminlvute'. I provide means for varyin the rate offeed 1n thismechanism whloi enables bale-ties of different lengt-hs to bemanufactured.

The frame of my vkmachine comprises pref-V erably a single castingformed of a base n membery 10 and a series of vertical bearing posts orstandards which will be described in connection with the parts supportedthereby. (In vbearings 11 and 12 formed in' two such posts is journaleda shaft 13 provided with fast and lloose pulleys 14 and 15 by which themechanism of the machine is driven. A spurV gear 16 on the end of shaft13 meshes with a spur gear on a short shaft held in bearings 18 and `19in the tops of verticalfstandards 20 vand 21 positioned in suchproximity as to leave space between v them only for the gear 17.A Theshaft in bearings 18 andi19` has formed on opposite ends thereoffand'extendingjust outside of bearings 18 and 19, bevelgears 22 and 23,

respectively. The bevel gear 23 meshes with va `bevel gear 24: on anoblique shaft 25 held in oblique bearings 26 and 27 in kthe ends ofstandards 28 and 29.

Upony the lower y end of shaft` 25 isa bevel gear 30 meshing' with abevel gear 31 on a shaft 32 mounted in bearings y34C, 35, 436, 37, and38 formed in short;standardsv provided kfor that purpose, the shaft 32extending transversely entirely across the machine near the front ordelivery end thereof. Between bearings 37 and 38 near the end of shaft32 farthest removed from gear 31 is a segment gear 39, formed, as shownin Fig. 4, of a gear segment proper 40 and an untoothed sect-ion 41,said sections being shown as cast separately and secured together bymeans of bolts 42 and 43 although it is obvious t-hat the gear may becast in one piece, the form shown being somewhat simpler in finishing. Ashort shaft 44 is mounted in bearings 45 and 46 in upright standards 47and 48, said shafthaving thereon between said standards a spur gear 49provided with a long tooth 50, said long tooth having a circular faceadapted to engage the face of the section 41 of mutilated gear 39 whichthereby holds gear 49 and shaft 44 in a definitely fixed position. `Whenthe teeth on section 40 come around to said wide tooth 50 they will becaused to mesh with the teeth on gear 49 and said gear and shaft 44 willbe turned a complete revolution by the gear segment 40, the peripheralextent of the toothed portions of both gears 39 and 49 being equal. Therim is cut away as indicated at 51 in Fig. 4 to permit the tooth 50 topass from locking engagement with the st-raight rim of section 41. Shaft44 is extended beyond bearing 46 as indicated at 52 and upon suchextended portion a spur gear 53 is removably secured by means of a nut54. In a bearing 55 in the top of a standard 56 is journaled a shortshaft 57 having removably secured thereto by means of nut 58 an idlerspur gear 59 meshing with spur gear 53 and also with a spur gear 60removably secured by a nut 61 on the extended end 62 of a shaft 63mounted in bearings 64 and 65 in the tops of standards 66 and 67.

The shaft 63 is the main feed shaft of the machine and it will be notedthat this shaft is driven from the cam shaft 32, which cam shaftcontrols the movements of the loop-forming mechanisms. The cam shaft 32is constantly driven from shaft 25, but the shaft 63 being actuated bythevsegment gear 39 on shaft 32 is intermittently driven, thecombination being such that shaft 63 will be rotated ywhile shaft 32 ismaking onehalf revolution, the other' half of the revolution of shaft 32being occupied in actuating the loop-forming and cutting meehanismshereinafter described. As the gears 53, 59 and 60 are all removable, itwill be obvious that by changing these gears the extent of revolution ofshaft 63 for each actuating semi-rotation of shaft 32 may be varied asdesired for feeding different lengths of bale-ties. The shaft 63 isformed with an enlarged shouldered portion 68. Secured against theshoulders of the enlarged portion 68 by means of a washer sleeve 69spiral gear 70 and nut 71 on shaft 63 is a feeding disk 72 providedwit-h a peripheral groove 73 which will preferably be V-shaped so as togrip the wire as it is fed through. Secured against the other shoulderof the enlarged portion 68 by means of a nut 74 on shaft- 63 is a spiralgear 75 similar to spiral gear 70. Spiral gear 70 meshes with a spiralgear 76 on a vertical shaft 77 held in bearings 78 on each side of gear76 in horizontally projecting brackets on one arm 79 of a stand 80secured to basemeinber 10, the arm 79 being similar to the other of saidarms 81 shown in elevation in Fig. 2. The gear meshes with a gear 82 ona shaft 83 held in bearings 84 in the horizontal brackets 85 of the arm81, as clearly shown in Fig. 2. Secured to shaft 83, so as to haverotation in a vertical plane, by means of a nut 86 is a grooved disk 87similar to the disk 72, a grooved disk 88 being secured to shaft 77 inexactly the same manner that disk 87 is secured to shaft 83. The bearingblocks 78 and 84 are secured in position by means of set screws 89 and90 as clearly shown in Fig. 1. The feed disks 87 and 88 extend in acommon horizontal plane at right angles to the plane of the disk 72, andhave their peripheries movable in such close proximity as to firmly gripa wire between the walls of the V-shaped grooves in the peripheries ofthese members, the set bolts 89 and 90 permitting adjustment of thesefeeding disks relatively to accommodate them to wires of differentsizes. As shown in Fig. 2, a coperating feed disk 91 similar to and inthe same plane with the disk 72 is mounted upon a shaft 92 in movablebearings 93 and 94 slidable in ways 95 formed in standards 96 and 97extending upwardly from the base member 10, the bearings 93 being forcedupwardly so as to cause the periphery of feed disk 91 yieldingly toengage the periphery of feed disks 72 by means of springs 98 seatedbetween said bearing blocks and a supporting block 99 adjustably carriedby bolts 100 and 101 extending through lugs 102-103 on standards 96 andthreaded through the extended ends of block 99. By screwing up on bolts100 and 101 the pressure of the feed disk 91 against feed disk 72 may bevaried to accommodate the feeding device to the character of wire beingfed through. Secured in a vertical plane to the side of the standard arm81 are a series of three straightening guide disks 104 which are formedwith edge grooves 105 as clearly indicated in Fig. 1. Upon a horizontalplatform on the stand are secured so as to rotate in a common horizontalplane a similar series of straightening feed rollers 106. The wirecoming from reel 107 on stand 108, therefore, must first pass betweenrollers 106 which straighten it in a horizontal plane and guide itbetween rollers 104 which straighten it in a verticalplane and in turnxguide it between feed disks 87 and 88 positively rotatedto grip the wirein a horizontal plane and forward it between-'feedrk disks 72 and 91,where the wire is grippedl y so that the wire is positively gripped andn wire accurately, which is absolutely essen` fed in both horizontal andvertical planes,

which taken in connection with the V-` shaped form of the peripheralgroove 73 with which all of the feed disksr are provided, positivelyfeeds the 7 wire forward without anyslippage exactly kthe same Adistanceat each,` cycle of operation regardless of the speed at which themachine is Lbeing driven. It is the special object of thisv fea-K tureof my invention that the wire which yconnesfrom the coil and is `alwaysmore orl less bent and kinked shall be straightened,

fed, and cut off in fixedy lengths while per mitting the machine to runat high speed.`

For'ins'tance, when this machine is operating to make fro-1n sixty toseventy bale-ties per'minute, the wire whilebeing fed may travel at arate ofoverva mile a minute. -It will be apparent that nothing exceptingan absolutely positive and reliable feed can be* depended upon tomeasure the lengths of tial in an eflicient machine for the purpose,

this vbeing especially true ,whenL it is called to mindl that the n'feeding device is intermittent, its momentum being checked and,

gained'at each cycle ofoperation, at which time there would be greatliabilityr ofslippage and irregularity. 'n

f The cam shaft "32 hasthereon a series of cams which will later bedescribed forautomatically presenting the loop-forming mechn anisms tothe proper .point for performing their functions duringv the timefeeding is not taking place. This arrangement, therefore, strictlycorrelatesy the feeding of the length of wire, the cutting of the samewhich also is operated from cam shaft 32, and forming of the loop, thecomplete cycle of operations always taking place at each full revolutionof cam shaft 32. That is every time that cam shaft 32 is rotated once'abaletie is looped, drawn out, cut off and discharged from the machine.`

vAs the wire 109 comes from the last set o feed disks 72 and 91, it ispassed through a hollow mandrel or shaft 110 which is supportedlongitudinally of the machine in bearings 111 and 112 formed in uprightstandards 113 and 114. The hollow shaft` 110 has thereon a collar'115rengaged by a washer 116 between which and bearing 111 4 is a spiralspring 117 whichwill push the they said shaft is forced yback againstthe.`

pressure of spring 117 by means provided for that purpose. A spur gear118 is rota tably secured to the shaft 110, and between `said .spur gearand a collar 119 adjacent the end of the shaft is journaled the ring 120of a yfloating shifter 121 provided yat its lower depending end with aroller 122 engaged by a `rface cam 123 onthe shaft `32.

The cam 123, as shown in Fig. 2, has for the major rpartfof itscircumference a cylinydrical face 124 of sufficient height to hold theshifter 121 and with it the shaft 110 yin theirrearward position, asindicated in v`face 126 which progressively pushes back shaft 110, thereason for which will be hereinafter stated. To prevent floating shifterv,121 turning with shaft 110 there issecured to thesaid-shifter abovethe ring 120 a bar arm 127 adapted to slide between lugs 128 on the topof standard 114. 'It is obvious that securing bar 127 to standardv 114so as v121 and permitting the shifter to slide along the bar would servethe same purpose. The

spur.l gear 118 is preferably a wide gear in mesh with an idler 129carried by a short shaft'130 journaled in bearings in the ends of twostandards 131, 132, the idler 129 in turn ymeshing with a'spur gear 133yon a shaft 134 journaled in bearings in the ends `toextend'between lugson the top of shifter f of similar upright standards 135, 136, the fshaft 134 having thereon intermediate the said uprights a bevel gear 137meshing with bevel gear 22. Through this arrangement of gearing,therefore, the hollowrshaft 110 is constantly driven fromy the bevelgear 22,

the movement of the shaft longitudinally, -f

above described, being along the spur' gear rconnection and, therefore,1n no way interfering with the continuous ydrive of shaft Journaled inbearings 138 and 139 in up-y right standards 140 and 141 so as to extendparallel with and directly above the cam shaft4 32 is a shaft 142 havingsecured on the end thereof a spur gear 143 in'mesh with the spur gear17, said gear 17 being suinciently wide to permit longitudinal movementof shaft 142 to the desired extent with#` out breaking the meshingengagement thereof. The shaft 142 is provided with collars 144 and 145between which is journaled the ring 146 of a shifter 147 having ontheend thereof a roller 148adapted to be engaged by a wing cam 149secured by a collar 150 to the cam vshaft 32. To the upper part ofbetween lugs 152 so as to slide freely there-y betweenand hold theshifter from turning shifter 147 is secured a bar '151 extending withthe shaft. A springf153-extends'be-l1'30 tween washers 154 and 155 looseon shaft 142 and normally presses the shaft so as to hold the same inthe position shown in Fig. 3. rhe wing cam 149 is shown most clearly inFig. 6 and is adapted through shifter 147 to force shaft 142 forward thedesired extent during a little less than one-fourth of the revolution ofcam shaft 32.

Mounted to slide in bearings 156, 157 on the ends of upright standards158, 159 is a square shaft 160 having on the end thereof a mandrel pin161. The shaft-s 160 and 142 are held in alinement and the mandrel 161alines with a central hole 162 in the end of shaft 142 so that when boththe shaft 160 and the shaft 142 are brought to their' most forwardposition the mandrel 161 will be positioned in the hole 162. Keyed tothe shaft 160 is the ring 163 of a shifter 164 having thereon a roller165 positioned to be engaged by wing cam 166 carried by a collar 167fast on cam shaft 32. As shown most clearly in Fig. 5, the wing cam 166is of such extent as to engage roller 165 and hold shaft 160 and mandrel161 in retracted position for slightly more than one-half of a completerevolution of cam shaft 32, and when the shaft 160 is not so retractedit is held in its forward position by means of a spring 168 positionedbetween the collar 163 and the bearing 157.

As clearly shown in Fig. 2, the wire after passing through hollow shaft110 extends beneath the point of mandrel 161 and beneath a stationaryshear blade 169 removably secured by bolts 170, 171 to upright posts172, 173 carried by a frame 174 adjustably secured to base member 10 bymeans of a bolt 175 extending through a slot 176 in the horizontal base177 of said frame member. The posts or standards 172 and 173 each has onthe inner face thereof a groove 178 and 179, respectively, in whichslide correspondingly shaped projections 180 and 181 on a block 182.vRemovably secured to the block 182 is a shear blade 183 adapted tocoperate with the stationary shear blade 169. Extending beneath block182 is the end of a lever 184 which is pivotally connected at 185 to thestandard 114 being bent as indicated at 186 to carry the lever above acam 187 on the cam shaft 32 adjacent cam 123 and between standards 141and 158. The shape of cam 187 is indicated in dotted lines in Fig. 2 andis such that the lever 184 is forced up carrying with it block 182 andcausing shears 169 and 183 to cut the wire immediately after the feedingaction produced by gear segment 40 on shaft 32 has been terminated.

The complete automatic operation of my device is as follows. Supposingthe loop ing action to have just been completed and the gear segment 40on shaft 32 to bejust engaging the side of tooth 50 on gear 49,

during Athe succeeding half revolution of shaft 32, through gears 49 and53, idler 59, spur gear 60 and spiral gears 70 and 75 on shaft 63 andspiral gears 76 and 82 on shafts 77 and 83, the feed disks 87 and 88,the feed disk 72 and with it feed disk 91 will be positively rotated tomeasure and feed forward a piece of wire to form a baletie oft-he'length desired. As cam shaft 32 has been revolved the high part oncam 187 is brought into engagement with arm 184 by which block 182 islifted to shear the wire just at the moment when the last tooth of gearsegment 40 has left gear 49 and feeding action is stopped by engagementof gear tooth 50 with the untoothed rim of segment 41. At the same timewing cam 166 will have been taken from engagement with roller 165 onshifter 164 so that spring 168 will force shaft 160 and mandrel 161inwardly above the wire 109. There will then be a short section of wire188 extending from mandrel 161 to the point where the wire was shearedadjacent shear member 169. Upon the end of shaft 142 is a hook 189 whichas Lshown in Fig. 1 is at the bottom of the shaft so that when the shaftis pushed forward said hook will come be neath` the wire section 188 androtation of the hook will wrap the wire about the mandrel 161. The camshaft 132 will immediately after the wire is cut and mandrel 161 isprojected bring wing cam 149 into engagement with roller 148 and throughshifter 1.47 will force shaft 142 inwardly against the pressure ofspring 153 until mandrel 161 enters hole 162 and hook 189 comes beneathwire end 188. The wing cam 149 is of such size and is so timed in actionrelative to the drive of shaft 142 that the hook 189 will make twocomplete turns before the cam 149 passes off of roller 148 and the shaft142 is retracted by spring 153. Two full loops of wire, therefore, arelaid upon the mandrel 161 and as the hook 189 is retracted from themandrel the remaining end of the wire will be left extending at an angleoutwardly from mandrel 161 as indicated at 190 in Fig. 2. By this timecam shaft 32 will have rotated to the position shown in Fig. 2 and aslight further rotation will bring roller 122 opposite the low portion125 which will permit spring 117 to force shaft 110 inwardly. As shownin Fig. 1, a hook 191 similar to hook 189 is formed on the end of shaft110. vWhen, therefore, the shaft is pressed forward this hook willengage the end 190 of the wire extending at approximately right anglesto the main shank of wire 109 and wrap said end several times about themain shank of wire 109. The adjustment of the stand 174 by means of bolt175 in slot 176 will have been such that this last wrapping movementwill completely use up the end 188 origid v l `time through -thetoothedvand non-toothed' ing` the mandrel 161 from the double coil of' wire.formed thereabout, and immediatelyr after said withdrawal gear segment40 will again have come into engagement with ytooth 50 on gear 49 andthe feeding action of another cycle of operations will be begun.

From the above it will be seeny that the hooks y189 and 191 whichperform looping operation are constantly rot-ated, but the controlof-.said hooks for' positioning them toV effect their function and yalsothe control of the mandrel 161 for positioning it to receive theiloopand for withdrawing it `fromsaid loop isv effected entirely bytherotationof ,cam shaft 82 which at the same segments 40 and 41 determinesthe feed of the wire in absolutely cordinated'relation to the' loopingmechanism and the shearing device, which is also controlled from the camshaft 32. A single member,therefore,

is provided for automatically controlling the operations for" projecting,the mandrel,

j forming-the loopfon the mandrel, wrapping the end of the wire aboutthe shank ofthe wire, measuring and feeding the wire of the properlength through the machine and then shearing the same. In view of thepositive ness and accuracy of the feed and the above indicatedunitarycontrol of all of theoperations of the machine, the Amachine isnot only rendered automatic in the fullest sense of the term but isautomatic to such an extent as to Vrequire practically no attention froman operator and to need merely an unskilled attendant for removing andcaring Vfor they bale-ties asformed and setting up a new roll of wire asthe preceding wire is used up. Economies in operation of the machinewill bey apparent and in-view of the results obtained, the machine issimple in structure and economical to build.
